The changes are incrementally small—small enough to easily explain away. One extremely hot summer could be just a fluke. An outrageous rain that floods streets is striking, but likely isolated. We live in a time when some countries are actively covering their glaciers to prevent melt, while others drill into oil reserves with reckless abandon.

But taken in sum, these flukes add up to something more. Sometimes you have to see it to believe it.

These arresting images show some of the most striking effects of climate change already underway.

Believe it.

Famished: San Diego, California

This bloom of krill, pink, fast, and alive, is already a rare sight in the North Pacific. But with warmer seas, they’ll become even rarer, here and elsewhere. The tiny crustaceans live in a narrow temperature band just 6 degrees wide. As the waters heat up and krill die off, other dominos in the marine food chain will start to topple; all manner of seabird, fish, and leviathan feast on the three-inch creature. In California, the local—and endangered—Scripps’s Murrelet depends on krill as a diet mainstay. As swarms like these disappear, there is no telling how the murrelet will adapt.

Flooded: Dorchester County, Maryland

The Chesapeake Bay, whose surf is spilling onto the roads of coastal Maryland here, has risen one foot over the 20th century. With water coming further inland, any squall is now more dangerous for coastal habitat and the wildlife living within it. The local American Bittern nests in the dense reeds of the area’s wetlands, but are now frequently battered by the waves. As storm surges around the world grow worse, it and other birds will soon find themselves without refuge. Photo Credit: Greg Kahn/Grain

Covered: Rhone Glacier, Switzerland

The Rhone Glacier has steadily shrunk for over 150 years. At this point, the situation is so dire scientists have resorted to covering the glaciers with heat-protective blankets during the summer months. Projects like this one at the Rhone Glacier in the Swiss Alps prevent the glacier from retreating further while also stopping glacial melt from entering the local watershed. The blankets are now common practice in many icy regions of the world. Photo Credit: Olivier Maire/EPA/Corbis

Punctured: Antarctic Ice Sheet

It’s not just atmospheric greenhouse gasses that heat up the earth—the bright white of the polar ice caps should also reflect solar rays back into space. But these snow-covered caps are increasingly interrupted by pits like these, whose black mud bottoms of rocky sediment called cryoconite drastically reduces polar surface reflectivity. As the ice is increasingly punctured by cryoconite, more and more heat is captured, melting increasing amounts of ice in a feedback loop that might spell the end of pack ice—one of our most important defenses to runaway climate change.

Fracked: Bakken Shale, North Dakota

The oil rush of the Bakken formation—the massive oil and gas-rich shale underneath Montana and North Dakota—is a new kind of environmental hazard: hydraulic fracturing, or fracking. The encroaching degradation shown here is just the surface wound. Fracking pumps chemicals and sand into the earth and explosively shatters the rock formation, releasing fuel that often finds its way into adjacent watersheds. Evidence is mounting that fracking can even induce earthquakes. The critically endangered Baird’s Sparrow is a denizen of this once pristine landscape. As oilrigs devour its habitat, its chances for survival grow slimmer and slimmer. Photo Credit: Tristan Spinski/Grain

Disbanded: Central Highlands of Iceland

Iceland has seen average temperatures increase by about 1.2 degrees Celsius since 1975, a rate four times that of the rest of the Northern Hemisphere. These opalescent streaks are actually rivulets of glacial meltwater, making their way from ice caps to the sea. The milky appearance comes from all the dissolved sediments, known as rock flour, once locked away in the ice. The tiny rivers’ beauty conceals a dark reality: The country’s more than 300 glaciers are losing 11 billion tons of ice a year. Photo Credit: Solent News/Splash News/Corbis

Overstocked: Arizona

Industrial farming now accounts for 80 percent of water usage in the United States alone. On top of water waste, livestock cultivation releases up to 94 million metric tons of carbon into the atmosphere globally, not to mention the millions of metric tons of methane, a far more potent greenhouse gas than CO2. The cattle seen in this field lot, stretching as far as the eye can see, both consume and produce CO2. As the global population grows, further agricultural intensification is inevitable.

Drained: Baja California, Mexico

The Colorado River delta once sprawled over 2 million acres in the southwestern United States and northwestern Mexico. These days severe drought, compounded by local agriculture’s profligate irrigation techniques, has slowed the river to a trickle by the time it hits the border. Follow the waterway to its basin on the Gulf of California, shown here, and much of the year all you’ll find is a desiccated riverbed. Since 2004 the 244,000-square-mile Colorado River watershed has lost 65 cubic kilometers of fresh water, mostly groundwater, or about three times the river’s yearly output into the gulf. Despite water-sharing pacts aimed at quenching the parched earth, the wetlands needed by birds like the Ridgway’s Rail could soon be a memory. Photo Credit: Peter McBride

Blighted: Central British Columbia

The forests of central British Columbia, where the Varied Thrush and Red-naped Sapsucker breed, are under attack. Warmer winters and unrelenting drought in western North America have led to a rampant mountain pine beetle outbreak, with no end in sight. The insects, which have infested more than 46 million acres in the United States alone, kill trees, creating vast quantities of kindling that feed wildfires, like the one whose scorched remains are seen here. Despite mitigation efforts, 7 million acres of infested pine trees still bear the blight’s telltale red foliage, and the province expects to lose 57 percent of its pine stands by 2021.

Torched: Rancho Santa Margarita, California

The U.S. wildfire season lasts a full two months longer than it did 40 years ago, and the heat is only going to intensify; brush fires charred 9 million acres in 2012 alone. Fire tornadoes—also called fire devils—like this one in Orange County, California, commonly form at the leading edge of blazes, shooting out burning debris. Their core temperatures can reach 2,000 degrees Fahrenheit, and their wind speeds can hit 100 miles per hour. Wildfire can bring new life—birds such as the Black-backed Woodpecker thrive in recently burned areas—but for the California Gnatcatcher, a threatened species limited to Southern California and Baja California, it means only trouble.

Melted: Chukchi Sea, Arctic

Black-legged Kittiwakes, seen here gathered on a melting ice sheet in the Chukchi Sea, breed in the Arctic. These seabirds, whose North American populations are decreasing, have better breeding success when sea ice cover is greater and the cold waters beneath produce more forage fish. As the region warms, kittiwakes are in store for more assaults, including new shipping lanes and increased oil and gas development—an estimated 350 billion barrels of oil sit beneath the Arctic seafloor. The threat of oil spills puts kittiwakes and other wildlife on even thinner ice. Photo Credit: Florian Schulz/Visions Of The Wild

Starved: Novaya Zemlya Island, Russia

The Arctic is warming at an unprecedented rate, and summer sea ice may disappear entirely within a few decades. This rapid retreat is stranding polar bears far away from seals, their main quarry. The bears, like this adolescent male scavenging Thick-billed Murre eggs on the cliffs of Russia’s Novaya Zemlya Island, have had to turn to new prey. It’s a seismic shift in the food chain, one polar bears may not be able to withstand: It takes 88 Snow Goose eggs (another newly susceptible species) to deliver the nutrition in one meal of seal. As for the murres, their hard-to-reach breeding sites have largely kept predators at bay. Until now. Photo Credit: Jenny E. Ross
